[NL20-NL50] NL25: 10-9os, 4 bet pot, FR

Ok well i'm wondering if my line on the flop is ok or weather i should just be check folding? Villain 3-bets pretty losse preflop (10%) but folds a lot to agression, this is why i am prefering to bluff 4bet than fold pre flop.

On the flop i have decent equity vs the range i put him on (pretty much pp9's, pp10's, ppJ's & less frequently Q's as i feel he would 5bet all in alot of the time). I don't like leading out on the flop because if i get raised i will have to call off and this only gives me one way to win. So i checked as i may either get a free card or could check raise. In the end villain tanked before calling, i was quite supprised to see him call with 10's. What do you think?

Doubt that you ever going to see him folding those hands for the given stack he has already put in. Rather just Check/Fold it cause his range may be very capped towards even trap and not only weak PPs.
